1. Identification of Unique Hematopoietic Stem Cell Properties
Abstract : Hematopoietic stem cells (HSC) are sufficient and required for life long production of all blood cell lineages. Steady state HSCs are largely quiescent and we demonstrate that the kinetics of HSC cell cycling are slower compared to more committed progenitor cells also during expansion and self-renewal ex vivo and in physiological conditions.

2. A Purkinje cell Timing Mechanism. On the Physical Basis of a Temporal Duration Memory
Abstract : The standard view of neural signaling is that a neuron can influence its target cell by exciting or inhibiting it. Learning is thought to involve strengthening or weakening synaptic connections. For most behaviors, the brain must learn to produce precisely timed activity patterns. READ MORE

3. Novel Interactors of X-linked Inhibitor of Apoptosis Protein : Expression and Effects on Tumor Cell Death
Abstract : Programmed cell death, or apoptosis, has during the last decade received a lot of attention due to its involvement in a large number of pathological conditions. Since death is always irreversible, it is important for cells to fully control the initiation and execution of this process. READ MORE

4. An Associative Memory Trace in the Cerebellar Cortex
Abstract : Classical conditioning of motor responses, e.g., the eyeblink response, depends on the cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the response.

5. The Cerebello-Olivary Feedback System
Abstract : The pathway from the deep cerebellar nuclei to the inferior olive, the nucleo-olivary pathway, is known to be inhibitory. The physiological and temporal properties, as well as the localisation, of the nucleo-olivary pathway were characterised in the decerebrate ferret. READ MORE
